Rear wheel conversion

[mwr2452]

Have '99 SV and want to put a wider rear tire/wheel combo. I want a more authoritarian look. My bike has lived two lives-first as a sprint road racer, now as my nimble little 600 killer on the streets.
I've read posts here about a Bandit 1200 rear wheel, but is that the 5.5" or the 6.0"?

I think you can also fit a cbr600f3 rear wheel with some spacers

....I want a more authoritarian look.....

You tried sitting up straighter and wearing shades? :rolleyes:

[NedSVS]

It's the 5.5 inch bandit 12 wheel with 180 rear tyre. This is tight so I don't think a 6.0 inch with 190 would fit. The CBR600F3 is only 5.0 inch and looks like this:

whats with the blocks under the side stand? ? is this just to make is sit up staight for the pic or soes the wheel mean its too high? ? ? :confused:

Just to make it stand more vertical for the photo's.

B12 is the way to go as far as I'm concerned, a 180 is pinched on the 5.0 Honda wheel and the fitment issues are similiar, plus the Honda one looks different to the SV one so you need to go further as Ned's done- the Bandit one is cosmetically identical to the SV. I think it's lighter, too.

I FINALLY got the ally tube i need to whip up a set of spacers for a Bandit 12 wheel, and I might actually do it some time soon, once I get that sorted I'll post full specs here.

You can do it 2 ways,, either a big steel spacer right through the middle to effectively enlarge the SV axle, or alternatively change bearings and spacers entirely for a more OEM, lightweight fit. I'd do option 2. It's more work and cost though.

I think a 5.5 will safely hold a 190 wheel, and I know 190s have been wedged into the SV arm, but I remember at least one of the people who did it ended up having to shave the tyre to fit :shaking: Just slightly, but... Well, it's bad juju as far as I'm concerned. 180 is big enough ;) Hell, 150 is big enough for the SV, it just looks stupid.

Be aware that it will impact handling. Some will say it'll make it worse, I won't, but it will definately affect it. Mine already turns faster than I can turn it so if it slows down a little I don't care.

Yes please.

Be warned, I've been saying much the same thing for about a year :rolleyes: I'll not be fitting it myself now- I've got a 929 Blade Dymag to fit instead, because that's the sort of fool I have become- but I still want to finish the job with teh Bandit. I've got 2 B12 wheels in the garage even :rolleyes:

about a year? is that all?? ;)

[northwind]

Well, I've been falling over the wheels for at least that long :rolleyes:

[zadar]

94/95 gsxr750 or gsxr's 1100 wheels look same also.

[northwind]

Very true. And I do believe there might be a kit available from Twin Works Factory for that just as with the F3 wheel, though I'm not 100% ;)

Rare as rocking horse poo though. I got my 2 B12 wheels for about ?40, though only one has a sprocket carrier. RF900 is the same as well, and come in a nice garish purple (luckily I scraped lots of the purple off learning hpw to change tyres)

Oversize wheel swaps ftw!

:laughat: northys pink bike

[northwind]

It's Triumph Red :D

[dirtydog]

Ah that'll be nuclear red

[northwind]

On my colourwheel it says "Big Gay Pink" :smt025

Just finished the first of the spacers for the B12 wheel, very crude- the pipe I'm using is too thin really, it's just for testing. It's definately too thin for the machining, bloody stuff bends in the jaws of my lathe so I had to do it all by hand... It also needs a modified SV sprocket carrier I think, 2 SV rear wheel bearings, and maybe some other stuff, I'll find out soon. I want to figure out my Dymag rear first though.

If you fit the wider rear it will not turn in as quick. trust me I fiied the 1200 Bandit wheel and now its back to the stock rear.
Just FYI a know Ducati riders who downsize rear tyres for this same reason. Biggest is not best in this case I assure you.

[northwind]

That's purely a matter of taste. If Billy will grace us with his presence for a moment he'll tell you the exact opposite. But others would definately agree with you.

Does your bike have any other work done to it? The reason I ask is that the SV has very conservative geometry to compensate for its rubbish suspension and to make it safe handling for newbies... But most people doing a mod like this will also have considered other stuff which will change the geometry and speed the turn in. Like I said up the page, mine turns faster than I can, so a reduction in turn-in speed isn't going to be a big consideration for me.

It also depends on tyres... Different tyres have different turn-in characteristics.

It never slowed the turn in on my SV but then mine was jacked up at the rear and had the SRAD front end!

And a pic!

Also you have a bigger foot print when cranked over so more grip:cool:

I can see that with standard geometry.

[northwind]

Uncanny, I've actually got my finger out. If I had the right sprocket, I could put this on the road today... Though not very durably, instead of making a proper sprocket carrier spacer I've just pressed a spacer into the stock B12 one, and it's just cheap ally so it's not really any use, just for testing.

Now, if anyone knows where I can find some decent thickness ally pipe, with a 17mm or very near and at least a few mm pipe thickness, I could make a proper one... My toy lathe isn't up to boring out the main spacer significantly unfortunately so I can't just make it from my bits of bar, I need a tube to start with. Also, a spare SV sprocket spacer- you could make one from scratch or press a steel spacer into the B12 one but it makes no sense, the SV one is the perfect size but just a few mm too long, so that'll turn down no probs if I had a spare.

In fact, if I can find that stuff I could make a few, the hard part is just working out the dimensions which is almost done. I could post up what I have but I prefer to actually have it fully done before telling people it'll work, I'm not that confident in my checking until I see it in situ.

Big bikes with big HP use big tyres to get the power down. We only want these for looks dont we. I just liked the look but did not like the change it made to the feel, personal choice. But the 180 does look good on the SV I must say.

Oh yeah, absolutely. Maybe if you're running a 110bhp 750cc SV then you'd not want to be on a 160, but you can easily find people running 150s on the rear of the SV- no shortage of grip and you get faster initial turn-in. But yeah, we certainly don't need it, if you feel like you want more grip this isn't the answer, just get a grippier tyre!

For my own bike, I'm doing it with a Dymag rear so as well as the looks it's also throwing off about a kilo and a half compared to the stock SV wheel with equivalent tyres... Which is nice! Also, it looks ace. The Bandit 12 wheel does add weight as well as tyre but it's not immense, the SV wheel is surprisingly heavy. I don't have the numbers on this though unfortunately, I've lost them.

With my 750 the 160 is great, its down to tyre choice not tyre size!!! Yes a 180 looks good on the SV but it is really for looks.

[northwind]

Yep, but then yours doesn't make 110bhp ;)

[Dangerous Dave]

Not as far as others....

[northwind]

Truth :cool: There's a demented french guy with a 110bhp street SV, can't recall if it's 750 or 800 but from what I understood of the translation it was a bit like war- short periods of great excitement followed by long periods of rebuilding :mrgreen:

Anyway, I think we can all agree that the best reason to fit a bigger rear tyre is to compensate for our small genitalia.

:laughat::pl:
ha,ha... yes I have to agree with that!!!

It was a 750cc, similair spec but not softened for reliabilty.

[Red Herring]

Another issue is tyre choice. I've just tried getting Dunlop D209 Qualifier RR"s and been told they don't make them in 160 rears, or the GP Racer spec either. Yes I know there are plenty of other brands to choose from but as there are fewer and fewer high performance sports bikes being produced with 160 rears then our tyre choice will slowly diminish.
